Well I had to give it a go of course! :lol:

The Helix Nebula (NGC 7293). Planetary nebula in Aquarius. Images 1st Sept 2014.

90 minutes of 3 minute sub-exposures taken with AT65EDQ, IDAS LPF and Nikon D5100 at ISO800. Bias and flat corrected.

I've also attached a crop of the nebula which is stretched to the max. I'm just starting to get a hint of the first outer shell. Given that is taken from my backyard in near-urban Canberra I'm pretty chuffed with how much I'm picking up.

Nice one Cam. Needs a little more data but great going.

Nice one Cam, doesn't look very forgiving though if that's 90 minutes of exposure :eyepop:

Don't forget that Cam is using a tiny scope Dunk. My 8" has ten times the
light gathering power.

Thank you all. Yes, it's a pea-shooter scope, so not much light gathering power. It also has to contend with my light polluted mag 4 to 4.5 skies. I am using an IDAS filter too which knocks back the light a little.

I can't wait to take this scope to a really dark site.
